In summary, your opinion is based on data which makes it valid and interesting, but I prefer the data from actual usage. Unless I am attacked in my home by Lime Jello-man intruders, I prefer to base my opinion on field data. The data on the site you refer us to is based on ballistic tests on gelatin. If there are any LEOs out there reading this who carry 9mm, I would appreciate their input. To my knowledge, police are using 115 and 124 grain HP. Please offer any data from police departments that are using that load to support your claim, and you will help convince me. I only agree that the more recent supersonic 147 rounds penetrate as well, but reiterate that they are yet unproven in the field. My source is Massad Ayoob- none better- as of 2008. Here's a good starting place for more info: **Pacific Tool & Gauge 9mm Throater - PT# 88841 Rev A.We're not in the 1980's anymore. The following is a listing of velocities we obtained in various 9mm firearms: Last but not least at 950 to 1000 feet per second this 180 grain bullet produces between 360 and 400 foot pounds of energy at the muzzle with very manageable recoil even in subcompact 9mm handguns. As I discovered with my own Glock 19 I will need a muzzle booster, or Nielsen device, to get the Glock to cycle with this ammo and a suppressor attached. While I developed this ammo specifically for use in suppressed firearms it cycles unsuppressed weapons as well. For those of you unfamiliar or skeptical about Hi-Tek Supercoat, I can attest to the fact that after firing thousands of rounds of coated bullets it virtually eliminates lead fouling, at least with all the subsonic ammunition that we load and shoot. Talking with my bullet caster who is a CZ fanboy claims all CZ’s are short throated and require using a piloted throat reamer** with a slight taper to create an adequate throat or freebore in his CZ’s, which in addition creates a nice leade into the barrel rifling improving accuracy by optimizing bullet alignment as the projectile enters the rifled portion of the barrel.Īccuracy for this heavy bullet at 100 yards out of a Keltec sub 2000, and an AR platform pistol, is 1 to 2 MOA. Of the numerous carbines, subguns and handguns we tested this ammo in, the CZ P09, exhibited this lead fouling. As a result, short throated barrels with little or no leade into the barrel rifling will quickly cause excessive leading in the throat area causing failure to feed successive rounds fully into the chamber. 230 inches so there is not much taper from the bullet-shank-diameter to the Meplat diameter. That being said, the Meplat on this projectile is. Designing that much weight into a 9mm projectile that stabilizes in the conventional twist rates found in today’s firearms, and still allowing enough case capacity to propel the bullet at a sufficient velocity took a minute. It also performs well in shorter-barreled handguns. Well, it only took me 20 years to pull it off, but I finally spent the time and the money to focus on this project and refined a 9mm subsonic load using a hardcast coated lead bullet that is heavy enough to build sufficient back-pressure to cleanly ignite a slow-burning gunpowder without exceeding SAMMI pressure specs for the 9mm, and cycles any semi or full-auto firearm that you shoot it in, all the while remaining subsonic. What I really wanted was one load that functioned and remained subsonic-quiet in all my suppressed 9mm firearms. Still, a load that would cycle my suppressed handgun would be supersonic in a 16” barrel carbine or subgun. As a result, I began loading my own 9mm with the heaviest projectile of the day, that being the 147 grain FMJ or Hollow Point. I recall buying numerous brands of 9mm ammo, claiming to be subsonic, and that were subsonic in most handguns, yet none of them remained subsonic in my Keltec Sub2000, or my 9mm machine guns. Back then, while suppressors were not uncommon in the circles that I ran in, consistently reliable subsonic ammunition was not so easy to come by. I have had the luxury of shooting suppressed firearms since the year 2000.
